Well done mikeactually for digging in and getting to the end, you look like a bit of a whippet mind :wink: raddogair that is an awesome training regime 8O
For me what the mental trouble is:
If it was 100km, I would be thinking that its doeable.
If it was 100 road miles I would think its doeable.
If was time unlimited I would dig in and drag my sorry "ss to the end.
But 100 miles, with the cutoffs, off road is a big ask.
I will keep it in the diary but I am stopping worrying about it and get a bit fitter and see how far I get.
cheers
